The invention relates to the technical field of liquid level observation, in particular to a multi-layer-segment simultaneous measuring sleeve and an observation well, and aims at solving the technical problems in the prior art that observation wells, geographical locations of which contain multilayered aquifers, have large economic and time costs, and engineering resources and personnel resourcesare wasted. The multi-layer-segment simultaneous measuring sleeve comprises a plurality of liquid measuring tubes which are sequentially communicated; each liquid measuring tube comprises a liquid storage part, a liquid permeable part and a sealing and blocking part which are sequentially communicated; the sealing and blocking part of each liquid measuring tube is communicated with the liquid storage part of the adjacent liquid measuring tube; the liquid permeable parts are used for being communicated with a liquid in the observation well to allow the liquid to permeate into the liquid permeable parts; the sealing and blocking parts can block channels of the liquid measuring tubes. The observation well comprises a liquid level measuring device and the multi-layer-segment simultaneous measuring sleeve. The liquid level measuring device is arranged in the multi-layer-segment simultaneous measuring sleeve. The liquid level measuring device comprises liquid level measuring sensors correspond to the liquid measuring tubes of the multi-layer-segment simultaneous measuring sleeve one by one.
Description
technical field [0001] The invention relates to the technical field of liquid level observation, in particular to a multi-layer section simultaneous measurement casing and an observation well. Background technique [0002] The current industrial technology and means can only conduct long-term observation of aquifers with different buried depths in the same geographical location, only through large-diameter wells and multiple casings for layered monitoring or multiple small-diameter single-casing drilling; this method It will cause great waste to the economic cost, time cost, engineering construction amount and artificial equipment scale of the observation well. [0003] Therefore, the present application provides a new multi-layer simultaneous measurement casing and observation well for the above-mentioned problems, so as to reduce the economic cost and time cost of observation wells for long-term observation of aquifers with different buried depths underground in the same g...
